LDO linear regulators deliver 500-mA in TDFN

Sunnyvale, Calif.—Maxim Integrated Products introduced the MAX8902A/MAX8902B, 500-mA, low-noise, low-dropout (LDO) linear regulators that are packaged in a tiny, 2mm x 2mm TDFN.

The MAX8902A/MAX8902B devices provide up to 92-dB PSRR (at 5kHz), 16 microVrms output noise, and a low, 100mV (max) dropout voltage at full load (500mA). The MAX8902A/MAX8902B are suitable for noise-sensitive and space-constrained applications, such as smartphones, PDAs, PMP/MP3 players, GPS devices, and ultra-mobile/notebook PCs.

The MAX8902A/MAX8902B offer ±1.5% output-voltage accuracy and a wide, 1.7V to 5.5V input-voltage range. The MAX8902A features preset pin-selectable output voltages between 1.5V and 4.7V, and the MAX8902B allows users to adjust the output voltage between 0.6V and 5.3V using two external resistors. To maximize battery life, these devices consume a low, 80 microamp operating current and less than 1 microamp shutdown current. Other features include a programmable soft-start circuit to prevent high inrush currents, short-circuit protection, reverse-current protection, and thermal shutdown.

Available in a thermally enhanced, 2mm x 2mm, 8-pin TDFN package, the MAX8902A/MAX8902B are fully specified over the -40°C to +125°C automotive temperature range.

Pricing: Starts at $1.25 (1000-up, FOB USA).
